Display device, display system and resolution adjusting method

Abstract

The present disclosure relates to a display device, a display system and a resolution adjusting method. The display device comprises a display screen, and further comprises: a distance sensor and an adjusting unit, wherein the distance sensor comprises: a particle emitter for emitting a first particle beam to a viewer; a particle receiver for receiving the first particle beam reflected by the viewer, and wherein the adjusting unit adjusts a resolution of the display screen based on an energy density of the emitted first particle beam and an energy density of the received first particle beam.

Description

[0001]The present application is the U.S. national phase entry of PCT / CN2016 / 070797, with an international filing date of Jan. 13, 2016, which claims the benefit of Chinese Patent Application No. 201510494589.X, filed on Aug. 12, 2015, the entire disclosure of which is incorporated herein by reference.FIELD[0002]The present disclosure relates to the field of display technology, particularly to a display device, a display system and a resolution adjusting method.BACKGROUND[0003]High PPI (Pixels Per Inch) is always an important target in the display field, and has once become an important selling point of products such as mobile phones and televisions. However, high PPI also brings some disadvantages while bringing advantages such as good viewing effect. High PPI would result in increase of the data processed by the GPU (Graphics Processing Unit), thereby resulting in large power consumption of the battery.[0004]Actually, the resolution of human eyes is not always invariable; it gener...

AI Technical Summary

Benefits of technology

The patent describes a technology that adjusts the resolution of a display screen based on the distance between the viewer and the screen. This reduces the power consumption of the display screen when the viewer is further away from the screen, while ensuring that the viewer has a good viewing experience.

Problems solved by technology

However, high PPI also brings some disadvantages while bringing advantages such as good viewing effect.

High PPI would result in increase of the data processed by the GPU (Graphics Processing Unit), thereby resulting in large power consumption of the battery.

However, when the screen is relatively far from the user, even if the resolution does not meet the above one, the user would not be able to identify the pixel points either; therefore, it is unnecessary to always keep the display screen at a relatively high resolution so as to result in excessive consumption of electricity.
